Description

Technical Field

[0001] The present invention belongs to the technical field of power equipment storage, and more specifically, particularly relates to a storage rack and method for power cable reels. Background Art

[0002] A power cable reel is a device used to wind and store power cables. It is mainly composed of a reel body (including two symmetrical discs and a cylindrical part connecting them), and its materials are usually wood, plastic, metal and other types. A storage rack is a device used to place and store items. In the power cable reel storage scenario, it is mainly a rack for placing power cable reels.

[0003] At present, the existing rack (such as announcement number: CN114313721B) discloses a storage shelf, which, through the cooperation of the arc-shaped fixed column and the connecting rod, can make the device when installed, by inserting the connecting rod into the inside of the connecting groove, so that the fixed bracket can be raised or lowered at any time to adjust the area where the items can be placed, and through the cooperation of the first movable baffle and the second movable baffle, when the device is installing the fixed bracket, the fixed rod can be inserted into the inside of the outer groove of the baffle, so that the installation between the upper and lower fixed brackets is more stable, and the fixed bracket is prevented from collapsing during installation to cause unnecessary danger; However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: when the device is used to store power cable reels, since the discs on traditional power cable reels do not have additional limiters to avoid accidental rolling, when placed on a shelf, the cable reel can only be placed on its side, which makes the contact area between the entire cable reel and the storage plate of the shelf too large and the friction is strong, which makes it inconvenient to take out or store. Summary of the invention

[0007] Preferably, the output shaft of each of the servo motors can drive the round shaft, the left-handed thread and the right-handed thread to rotate and generate threaded transmission with the transmission block. The inner wall of each storage slot is symmetrically provided with limit slots, and a limit block is slidably installed inside each limit slot. Each limit block is located on both sides of the transmission block.

[0008] Preferably, each of the limit blocks is fixedly installed with the transmission block, and each of the transmission blocks can drive the limit block to slide laterally inside the storage slot and the limit slot respectively. The first placement plate, the second placement plate and the third placement plate are symmetrically provided with sliding grooves, each of the sliding grooves is located on both sides of the circular axis, and a slider is slidably installed inside each of the sliding grooves.

[0009] Preferably, each of the sliders can slide transversely inside the slide groove, and a transmission plate is fixedly installed between each of the sliders, each of the transmission plates is located above the transmission block, and each of the transmission plates is fixedly installed with the transmission block.

[0011] A working method of a placement rack for a power cable reel stack, comprising the following steps: When the cable drum needs to be stored, the servo motor is turned on to make the output shaft start to rotate, thereby driving the circular shaft to rotate; as the circular shaft rotates, the left-handed thread and the right-handed thread perform threaded transmission with the transmission block, so that the two transmission blocks move toward each other in the circular groove; the movement of the transmission block drives the limit block to slide in the storage groove and the limit groove, and at the same time drives the transmission plate and the clamping plate to move until the long stop bar is located inside the cable drum rolling groove 27 and the short stop bar is located outside the cable drum rolling groove; the cable drum is lifted by a sling, and the two discs of the cable drum are aligned with the cable drum rolling groove, and are rolled and placed along the direction of the long stop bar; the servo motor is started again to make the transmission blocks continue to move toward each other until the clamping plate clamps the disc at the cable drum rolling groove; When the cable drum needs to be taken out, first start the servo motor to move the transmission blocks in opposite directions, and the clamping plates release the clamping of the cable drum disc; use the lifting device to lift the cable drum close to the short stop bar.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by integrating the placement structure into the placement tray as a whole, the overall structure is compact, which is convenient for welding and installation on the existing bracket group. At the same time, due to the overall arrangement of the first placement tray, the second placement tray and the third placement tray stacked from top to bottom, the staff can not only stack them in one area, but also each layer of cable trays can be taken out by rolling, which is greatly convenient for later use. In the present invention, since there are usually symmetrically arranged discs on the outer side of the cable drum, by opening the cable drum rolling grooves inside the first placement disk, the second placement disk and the third placement disk, the staff can align the cable drum discs with the cable drum rolling grooves and place them in an array, so that when the cable drum is placed or taken out, the cable drum can be rolled in the cable drum rolling groove to reduce friction, thereby avoiding the problem of excessive friction between the side wall of the cable drum and the first placement disk, the second placement disk and the third placement disk, resulting in damage; In the present invention, by turning on the servo motor, the output shaft of the servo motor can drive the round shaft to rotate. During the rotation of the round shaft, the left-handed thread and the right-handed thread also rotate accordingly. Since the left-handed thread and the right-handed thread rotate in opposite directions, they perform thread transmission with the transmission block, so that the two transmission blocks on the third placement disk gradually approach each other, driving the transmission plate and the clamping plate to gradually approach each other, so that the disk at the rolling groove of the clamping wire disk can be clamped, thereby preventing the cable disk from shaking on the first placement disk, the second placement disk and the third placement disk, so as to improve reliability; In the present invention, by setting the limit groove and the slide groove, the servo motor and the driving shaft rotate, and the left-handed thread and the right-handed thread will be threaded with the transmission block, and the transmission block will drive the limit block to slide in the storage groove and the limit groove respectively. During the sliding process, the limit block drives the transmission plate to move, so that the transmission plate drives the slider to slide in the slide groove, thereby providing additional limit and increasing stability. In the present invention, by respectively arranging long baffle bars and short baffle bars on the clamping plate, the staff can turn on the servo motor to drive the transmission plate to move when placing the cable drum, so that the clamping plate, the long baffle bars and the short baffle bars on the transmission plate also move; when the long baffle bars are located inside the cable drum rolling groove and the short baffle bars are located outside the cable drum rolling groove, the staff stops the servo motor, and at this time, the cable drum can be prevented from falling out of the third placement drum when rolling from the short baffle bars to the long baffle bars, thereby improving safety.

DETAILED DESCRIPTION

[0015] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] See also Figure 1 - Figure 7The present invention provides a placement rack for a power cable tray stack, comprising a bracket group 32, wherein a first placement tray 11, a second placement tray 12 and a third placement tray 13 are fixedly installed between the bracket groups 32, and the first placement tray 11, the second placement tray 12 and the third placement tray 13 are stacked from top to bottom on the bracket group 32, and a circular groove 14 is respectively opened inside the first placement tray 11, the second placement tray 12 and the third placement tray 13; A placement structure is rotatably mounted inside each circular groove 14; The placement structure includes a circular shaft 15, and a servo motor 16 is fixedly installed on the side walls of the first placement plate 11, the second placement plate 12 and the third placement plate 13. Each circular shaft 15 is fixedly installed with the output shaft of the servo motor 16. A placement groove 17 is symmetrically penetrated through the inner wall of each circular groove 14, and each placement groove 17 is rectangular. A left-handed thread 18 and a right-handed thread 19 are respectively provided on the circumferential surface of each circular shaft 15, and each left-handed thread 18 and right-handed thread 19 are located at both ends of the circular shaft 15. By integrating the placement structure as a whole on the placement plate, the overall structure is compact, which is conducive to welding and installation on the existing bracket group 32. At the same time, due to the overall arrangement of the first placement plate 11, the second placement plate 12 and the third placement plate 13 stacked from top to bottom, the staff can not only stack them in one area, but also each layer of cable trays can be taken out by rolling, which is greatly beneficial for later use.

[0017] Each left-handed thread 18 and right-handed thread 19 are located inside the storage groove 17, and a transmission block 21 is slidably installed inside each storage groove 17. Each transmission block 21 is threadedly installed with the left-handed thread 18 and the right-handed thread 19 respectively. The output shaft of each servo motor 16 can drive the round shaft 15, the left-handed thread 18 and the right-handed thread 19 to rotate and transmit threadedly with the transmission block 21. The inner wall of each storage groove 17 is symmetrically provided with a limit groove 22, and a limit block 23 is slidably installed inside each limit groove 22. Each limit block 23 is located on both sides of the transmission block 21, and each limit block 23 is fixedly installed with the transmission block 21. Each transmission block 21 can drive the limit block 23 to slide horizontally inside the storage groove 17 and the limit groove 22 respectively. The first placement plate 11, the second placement plate 12 and the third placement plate 13 are symmetrically provided with sliding grooves 24. Each slide groove 24 is located on both sides of the circular shaft 15, and a slider 25 is slidably installed inside each slide groove 24. Each slider 25 can slide horizontally inside the slide groove 24. A transmission plate 26 is fixedly installed between each slider 25. Each transmission plate 26 is located above the transmission block 21. Each transmission plate 26 is fixedly installed with the transmission block 21. By setting the limit groove 22 and the slide groove 24, the servo motor 16 and the circular shaft 15 are driven to rotate. At this time, the left-handed thread 18 and the right-handed thread 19 will be threadedly driven with the transmission block 21. At this time, the transmission block 21 will drive the limit block 23 to slide inside the storage groove 17 and the limit groove 22 respectively. During the sliding process, the limit block 23 drives the transmission plate 26 to move, so that the transmission plate 26 drives the slider 25 to slide inside the slide groove 24, thereby providing additional limit and increasing stability.

[0018] Wire drum rolling grooves 27 are symmetrically provided inside the first placement tray 11, the second placement tray 12 and the third placement tray 13, and each group of wire drum rolling grooves 27 is located between the slide grooves 24. Since there are usually symmetrically arranged disks on the outer side of the cable drum, by providing wire drum rolling grooves 27 inside the first placement tray 11, the second placement tray 12 and the third placement tray 13, the staff can align the disks of the cable drum with the wire drum rolling grooves 27 and place them in an array. As a result, when the cable drum is placed or taken out, it can be made to roll in the wire drum rolling grooves 27 to reduce friction, thereby avoiding the problem of damage caused by excessive friction between the side walls of the cable drum and the first placement tray 11, the second placement tray 12 and the third placement tray 13.

[0019] A clamping plate 28 is fixedly installed on the upper end of each transmission plate 26. By turning on the servo motor 16, the output shaft of the servo motor 16 can drive the round shaft 15 to rotate. During the rotation of the round shaft 15, the left-handed thread 18 and the right-handed thread 19 also rotate accordingly. Since the left-handed thread 18 and the right-handed thread 19 rotate in opposite directions, they perform thread transmission with the transmission block 21, so that the two transmission blocks 21 on the third placement disk 13 gradually approach each other, driving the transmission plate 26 and the clamping plate 28 to gradually approach each other, so that the disk at the rolling groove 27 of the clamping wire disk can be clamped, thereby preventing the cable disk from shaking on the first placement disk 11, the second placement disk 12 and the third placement disk 13, so as to improve reliability.

[0020] A long baffle 29 and a short baffle 31 are fixedly installed on the side walls of each storage groove 17. By respectively arranging the long baffle 29 and the short baffle 31 on the clamping plate 28, the staff can turn on the servo motor 16 to drive the transmission plate 26 to move when placing the cable reel, so that the clamping plate 28, the long baffle 29 and the short baffle 31 on the transmission plate 26 also move. When the long baffle 29 is located inside the cable reel rolling groove 27 and the short baffle 31 is located outside the cable reel rolling groove 27, the staff stops the servo motor 16. At this time, the cable reel can be prevented from falling out of the third placement tray 13 when rolling from the short baffle 31 to the long baffle 29 side, thereby improving safety.

[0021] Working principle: The first step is that in the actual working environment, the staff turns on the servo motor 16, and the output shaft of the servo motor 16 starts to rotate, driving the round shaft 15 to rotate. During the rotation of the round shaft 15, the left-handed thread 18 and the right-handed thread 19 also rotate accordingly. Since the left-handed thread 18 and the right-handed thread 19 rotate in opposite directions, they perform thread transmission with the transmission block 21, so that the two transmission blocks 21 on the third placement disk 13 gradually approach each other, and the movement of the transmission block 21 drives the limit block 23 to slide inside the storage groove 17 and the limit groove 22 respectively. During the sliding process, the transmission block 21 drives the transmission plate 26 to move, and the clamping plate 28, the long stop bar 29 and the short stop bar 31 on the transmission plate 26 also move. When the long stop bar 29 is located inside the wire drum rolling groove 27 and the short stop bar 31 is located outside the wire drum rolling groove 27, the staff stops the servo motor 16; By respectively arranging the long stop bar 29 and the short stop bar 31 on the clamping plate 28, when placing the cable drum, the staff can turn on the servo motor 16 to drive the transmission plate 26 to move, so that the clamping plate 28, the long stop bar 29 and the short stop bar 31 on the transmission plate 26 also move. When the long stop bar 29 is located inside the cable drum rolling groove 27 and the short stop bar 31 is located outside the cable drum rolling groove 27, the staff stops the servo motor 16. At this time, it can be prevented that the cable drum will fall out of the third placement drum when rolling from the short stop bar 31 to the long stop bar 29 side. 13, thereby improving safety, and by setting the limit groove 22 and the slide groove 24, the servo motor 16 and the driving shaft 15 are rotated, at this time the left-handed thread 18 and the right-handed thread 19 will be threadedly transmitted with the transmission block 21, at this time the transmission block 21 will drive the limit block 23 to slide in the storage groove 17 and the limit groove 22 respectively, and the limit block 23 drives the transmission plate 26 to move during the sliding process, so that the transmission plate 26 drives the slider 25 to slide in the slide groove 24, thereby providing additional limit and increasing stability.

[0022] The second step is that the staff uses the lifting device to lift the cable drum, places the two discs of the cable drum between the cable drum rolling grooves 27 of the third placement disk 13, and rolls toward the side of the long baffle 29. During the placement process, the staff carefully observes the rolling direction and position of the disc to ensure that the disc can be accurately placed between the cable drum rolling grooves 27. Subsequently, the staff repeats the above steps to place the remaining cable drums on the third placement disk 13 in turn. When the third placement disk 13 is full of cable drums, the staff turns on the servo motor 16 again, and the output shaft of the servo motor 16 drives the round shaft 15 to rotate. The round shaft 15 drives the left-handed thread 18 and the right-handed thread 19 to rotate and perform thread transmission with the transmission block 21, so that the two transmission blocks 21 on the third placement disk 13 approach each other again, and the transmission plate 26 and the clamping plate 28 gradually approach each other until the clamping plate 28 clamps the disc at the cable drum rolling groove 27. During the placement process, the staff pays attention to the position and state of each disc to ensure that the disc can be clamped and fixed. Subsequently, the staff repeats the above steps to stack them on the second placement disk 12 and the first placement disk 11 to complete the placement; By providing the cable drum rolling groove 27 inside the first placement disk 11, the second placement disk 12 and the third placement disk 13, the staff can align the cable drum disc with the cable drum rolling groove 27 and place it in an array, so that the cable drum can roll in the cable drum rolling groove 27 when being placed or taken out, thereby reducing friction, thereby avoiding the side wall of the cable drum and other parts from being damaged by excessive friction with the first placement disk 11, the second placement disk 12 and the third placement disk 13. Since the left-handed thread 18 and the right-handed thread 19 rotate in opposite directions, they are threadedly driven with the transmission block 21, so that the two transmission blocks 21 on the third placement disk 13 gradually approach each other, driving the transmission plate 26 and the clamping plate 28 to gradually approach each other, thereby clamping the disc at the cable drum rolling groove 27, thereby avoiding the cable drum from shaking on the first placement disk 11, the second placement disk 12 and the third placement disk 13, thereby improving reliability.

[0023] In the third step, when the staff needs to take out the cable drum, first use the lifting device to lift the cable drum near the short stop bar 31. During the lifting process, the staff carefully operates the lifting device to ensure that the cable drum can be lifted smoothly. Then, the staff turns on the servo motor 16 again, and the two transmission blocks 21 on the servo motor 16 drive the transmission plate 26 and the clamping plate 28 to move away from each other, canceling the clamping state of the cable drum disc, and finally, the staff takes out the cable drum; By integrating the placement structure into the placement tray as a whole, the overall structure is compact, which is convenient for welding and installation on the existing bracket group 32. At the same time, due to the overall arrangement of the first placement tray 11, the second placement tray 12 and the third placement tray 13 stacked from top to bottom, the staff can not only stack them in one area, but also each layer of cable trays can be taken out by rolling, which is greatly beneficial for later use.

[0024] Based on the above content, a working method of a placement rack for a power cable reel stack includes the following steps: When the cable drum needs to be stored, the servo motor 16 is turned on to make the output shaft start to rotate, thereby driving the round shaft 15 to rotate; as the round shaft 15 rotates, the left-handed thread 18 and the right-handed thread 19 perform threaded transmission with the transmission block 21, so that the two transmission blocks 21 move toward each other in the circular groove 14; the movement of the transmission block 21 drives the limit block 23 to slide in the storage groove 17 and the limit groove 22, and at the same time drives the transmission plate 26 and the clamping plate 28 to move until the long stop bar 29 is located inside the cable drum rolling groove 27 and the short stop bar 31 is located outside the cable drum rolling groove 27; the cable drum is lifted by a sling, the two discs of the cable drum are aligned with the cable drum rolling groove 27, and are rolled and placed in the direction of the long stop bar 29; the servo motor 16 is started again to make the transmission block 21 continue to move toward each other until the clamping plate 28 clamps the disc at the cable drum rolling groove 27; When the cable drum needs to be taken out, the servo motor 16 is first started to move the transmission blocks 21 in opposite directions, and the clamping plates 28 release the clamping of the cable drum disc; the cable drum close to the short stop bar 31 is lifted by a lifting device.

Many modifications and variations will be apparent to those of ordinary skill in the art.
